It can make large numbers of gas attempered to temperature required rapidly and ensure the cooling water to vapor and overheat completely avoiding the depressurizer of minute orifices' blocking. The attemperator combined with the depressurizer also can meet operation requirement under variant loads.

提出的高速文丘里雾化冷却器与小孔型节流降压消音器相结合的减温减压装置在中试电站的成功运行表明，采用高速文丘里雾化冷却方式能够充分利用高温高压烟气的能量雾化冷却水，既能使大气量的烟气快速降温，又能确保烟气的干度，安全地实现不同工况下含尘烟气的减温减压排放。

To study technology of spray drying in decompression and freeze for making microcapsule of cyminum essential oil,choice and combination of wall material,dose of core material filled,homogeneization pressure,times and pivotal parameters of spray drying in decompression and freeze were respectively in vestigated.

介绍了喷雾减压冷冻干燥法生产孜然精油微胶囊的工艺技术，通过实验分别对壁材的选择组合、心材的填加量、均质压力次数及喷雾减压冷冻干燥法各项参数的研究，最终确定了最佳的工艺条件，微胶囊产品达到了预期的效果。

Strut-graft with an appropriate distraction after corpectomy plays an important role not only in regain and maintain the cervical spine lordotic curvatures but also in acquire the global immediate stability of the cervical spine. After single vertebra corpectomy, the proper range of distraction between the superior and inferior vertebra maybe among 4-6 millimeters.

中下颈椎单椎体次全切除减压后，适当高度的撑开植骨对恢复和维持颈椎曲度以及手术节段的即刻稳定性有重要作用，中下颈椎单椎体次全切除减压后支撑植骨的高度应该是在手术椎体的上位和下位椎体间高度的基础上再撑开4～6mm左右。

The natural gas automobile decompressor is a natural gas automobile important part, its quality quality vehicle performance has the very big relations, it is main the reduced pressure in the natural gas automobile and the constant voltage function.

天然气汽车减压装置是天然气的汽车的一个重要部件，它的质量好坏车的性能有很大的关系，它在天然气汽车中主要起减压和稳压的作用。

When the load smaller than the first outlet pressure adjustment valve set pressure, pilot valve Poppet head off an oil chamber, oil chamber 2 is equal to the pressure on the outlet pressure, the main valve of the sliding shaft 2 inside the cavity in the oil a rigid under the action of a small spring at the lowest position, the main valve and the valve slider protruding shoulder posed by all the valve port opens, pressure reducing valve without decompression.

当负载较小，出口压力低于先阀的调定压力时，先导阀的提动头关闭，油腔1、油腔2的压力均等于出口压力，主阀的滑轴在油腔2里面的一根刚性很小的弹簧作用下处于最低位置，主阀滑轴凸肩和阀体所构成的阀口全部打开，减压阀无减压作用。
